Hi IHopeNot,
Welcome to the board. I'm so sorry to hear your story.

First let me say I hope you have some good, active support for recovering from having been raped. If you don't have that, I really encourage you to see a counsellor for this. If you don't know where to find someone, call a rape crisis line and they will probably be able to refer you or help you find someone. They might be able to help you find medical support for your symptoms too, if you have trouble getting diagnosed.
Your symptoms might be a lot of things, only one of which could be herpes. One thing I'd recommend is to get a type-specific blood test for herpes. This can tell you what types of HSV you have. HSV-1 is something most of us have in the form of cold sores (a.k.a. fever blisters), usually caught in early childhood. You might have caught this from the man who raped you, or the stress of the incident might have simply brought out the virus you already had into an outbreak. There's no way to know for sure.
If he had genital HSV-2 (the most common cause of genital herpes, but sometimes is caused by HSV-1) and you caught this from him, then HSV-2 should show up in a type-specific blood test. It would pretty much confirm that's what your symptoms are. If you test negative for HSV-2, your symptoms still might be HSV-1 but a blood test won't tell you if you have it in more than one location (i.e., orally and genitally).
A swab test on relatively fresh symptoms (ideally within a couple of days of when they first appear) can potentially confirm that, but swabs are famous for being hard to get a positive diagnosis from. You might have to try several times before you get a positive diagnosis...assuming that's what you have.
Symptoms of herpes are a little different for everyone. Check out the Resource Links for this board, which can give you some good information about common symptoms. Herpes.org is a good site for solid information.
A doctor could possibly offer alternative diagnoses of what it is, if it's not herpes. Do see a doc ASAP so that you can find out what it is. Please let us know what you find out. Good luck!
